GAS HEATED YHOT WTER RADIATOR Filed; Nov. 20., 1950 D f P -j' A n 11111 1111 Patented Dec. 1, 1931 UNITED sTATEs PATENT oFFlcE ANTONI WILHELM IKBUL, F TBE BAGUE, NETHERLANDS GAS HEATED HOT WATER RADIATOR Application led November 20, 1930, Serial No. 497,015, and in the Netherlands October 11, 1929.

The invention relates to a hot-water radiator adapted to be gas heated and has for its object to so construct this radiator that a largeheat-generation requires but a small gas-consumption.

The invention consists in that in a hot water radiator use is made of a gas burner, the lbody of which is inserted in a `connection between the lower ends of two groups of radiator elements in such a manner that the said connection at the burner body forms a water jacket which is integral with the burner body itself; By reason of the fact that the burner flames rapidly bring the burner body and its water jacket to a high temperature and that by heat conduction through the metal of the connection the lower ends of the radiator elements will also be intensively j heated, an increased Water circulation is produced. This circulation can be maintained by means of a small flame and consequently a small gas consumption. A greater part of the heat generated by t-he burner than in hot' I water radiators of the known type compr1sing an independent burner, is now utilized for heating the lower portion of the radiator elements, which is most favourable for the circulation.

In order to facilitate the manufacture and 4 stitutes the above mentioned connection which at the place of the burner body forms a water jacket that is integral with the burner body itself. In the said double walled water chamber the combustion gases ascend,

" the path of which may be lengthened by means of a partition which compels the gases to iirst iiow upwards and then downwards along the other side of thepartition towards the outlet. In one of the walls of the water chamber an aperture, adapted to be closed,

may further `be provided so that the burner table may be removed for cleaning purposes or the like. The burner table forms in the usual manner a separate piece adapted to be positioned on the burner body into which it may extend down into the mixture chamber with a pocket shaped extension.

The invention will be more fully understood with reference to the accompanying drawings illustrating it by way of example. o

Fig. 1 is a side elevation partly in section of a hot water radiator with gas burner according to the invention.

Fig. 2 is on a larger scale a vertical section of the gas burner with water jacket and connections separately.

Fig. 3 is a horizontal section on the line III- III in Fig. 2.

Fig. 4 is a section on the line IV'-IV in Fig. 5 of a double walled water chamber with 70 gas burner constructed as a unit in accordance with the invention.

Fig. 5 isa section perpendicular to Fig. 1. Fig. 6 is a horizontal section on the line VI-VI in Fig. 5. l 75 The apparatus according to Fig. 1 comprises a gas burner l which as shown in Figs.

2 and 3 is provided with a burner table 2 having the usual apertures 3 and an extension Q1, integral with the burner table 2, closed 80 at the bottom and of tubular formation. This extension is located in a mixture chamber 5 which is confined by the inner wall 6 of a water jacket 7 the outer wall of which is denoted by 8.

The gas and air mixture is supplied through a pipe 9 to the mixture chamber 5. The' water jacket 7 is connected by passages 10fand 11 at its sides to the lower ends of two groups of radiator elements each comprising four elements indicated by 12 and 13. vThe connection is established by means 'of left and right handed screw threads 14 and 15. The radiator elements 12l and-13 are at the top j interconnected by a connecting piece 16 which 95 to this end may also4 be provided at its ends with left and righthanded screw thread. The connecting piece 16 is centrally connected by a downwardly directed passage 17 to the water space of a double walled bell-shaped container 18, which at the bottom at either side of the burner -1 is'c'onnected by passages `19, 2O to the passages 10 and 11, communicatin with the water jacket 7. The container 5 18 is ocated centrally above the burner 1 so 'that the combustion gases will ascend in the interior space 21 of the container, from which space they are discharged through discharge openings 22 located at different heights and 1 enter a cap 23 enclosing the container 18 and having a discharge 24 to a stack not shown. 25 indicates a water storage tank mounted Qn the connecting piece 16 and connected to the passage '11 b .a conduit 26.

In the tank 2 an expansion tube 28 is arranged the upper end of which is bent Ain U- shape. When the 'gas burner 1 has been lighted and after the water jacket and thereby the connecting conduits and the lower ends ofthe radiator'elements have been heated to a high temperature by heat conduction, a strong circulation from the groups of radiator elements 12, 13 throu h th'e passages 19, 20 into the water space o the container 18,

16 and then into the upper ends of the radiatorelements 12, 13 will be maintained. The combustion vgases are also utilized for the perature become too high and steam be produced inthe radiator, then the steam can .escape from the connecting piece 16 through the tube 28 into the water tank 25 and fresh water may be supplied to the connecting piece 11 :through the conduit 26.

In Figs. 4-6 an element is shown by way of example, which forms an individual unit and 1s ladapted to be connected at either side l through 'the passage 17 and the connections heating of the container 18. Should thetem ieces 31 for 4connecting it connecting the said elements at either side to one radiator element or two elements, three ing and is then insertedlin the circulation of the central heating system.

I claim 1. A hot water system, comprising two roups of radiator elements, connecting memupper ends of said elements, a double-walled water heating container locatedbetween the groups of radiator elements and connected to the upper and lower connecting members, and a burner below the container, the body of the burner having a water jacket connected to the radiator elements.

2. A hot water system as set forth in claim 1, including a water storage tank, a conduit between the upper connecting member and the water storage tank, anexpansion tube in .the water tank, whereby steam from the upper connecting member may escape through the expansiontube to said tank, and a conduit from the bottom of the water storage tank to the lower connecting member, whereby water from the storage tank may replenish the circulating water.

' In testimony whereof I affix my signature.
